Measuring 1-5\/8 inches by 1-3\/4 inches, it provides a reliable seal in applications where water exposure and mechanical wear are ongoing concerns. Buna-N (nitrile) rubber is a standard material for plumbing O-rings because of its resistance to water swell and abrasion. The part is black in color and sold individually. Plumbers and experienced DIYers reach for this O-ring when restoring a watertight seal on leaking faucets or valves.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and light commercial faucet repair work. It fits into standard O-ring grooves on faucet stems, valve bodies, and related plumbing components where a size 52 O-ring is specified. Typical install scenarios include replacing a worn or cracked seal during a dripping faucet repair or a valve rebuild. Its Buna-N composition holds up in cold and hot water lines within normal residential temperature ranges.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (nitrile) rubber construction resists water swell and abrasion\u003c\/li\u003e\n  \u003cli\u003eSize 52 O-ring — 1-5\/8 inches inner dimension by 1-3\/4 inches outer dimension\u003c\/li\u003e\n  \u003cli\u003eBlack color, standard for plumbing and faucet applications\u003c\/li\u003e\n  \u003cli\u003eSold individually per bag\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement O-ring for faucets and valves requiring a size 52 Buna-N O-ring with 1-5\/8 inch by 1-3\/4 inch dimensions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or a knowledgeable DIYer. Shut off the water supply at the fixture stop valve or main before disassembling any faucet or valve. Inspect the O-ring groove for debris or damage before seating the new ring, and apply a light coat of plumber-grade silicone grease to help the O-ring seat evenly and extend service life. Do not use petroleum-based lubricants, as they can degrade Buna-N rubber over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile) Rubber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 1-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eO-Ring Size\u003c\/strong\u003e: 52\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00037155357666\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DANCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 35766B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DANCO","offers":[{"title":"Default Title","offer_id":51346552848690,"sku":"35766B","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310548660.jpg?v=1782083648","url":"https:\/\/voomisupply.com\/products\/danco-35766b-buna-n-o-ring-1-5-8-x-1-3-4-in-faucet-repair","provider":"Voomi Supply","version":"1.0","type":"link"}
